NO.83 An engineer prepares a set of Python scripts to interact with network devices. To avoid network performance issues, the engineer wants to run them in a test environment. Which resource must be used to monitor the live execution of code in an always-available environment?

packet tracer

learning labs

sandbox

code exchange

Comprehensive Detailed Step by Step Explanation with ReferencesA sandbox environment is an isolated testing environment that mimics a live network. It allows engineers and developers to run scripts and test code without affecting the production network. Cisco provides sandboxes through the DevNet portal, which are always available for testing and experimentation with network automation and programmability. Using a sandbox helps monitor the live execution of code in a controlled and safe manner, ensuring that any potential issues do not impact the actual network.

NO.84 Users cannot access a webserver and after the traffic is captured. the capture tool shows an ICMP packet that reports “time exceeded in-transit”. What is the cause of this webserver access issue?

A router along the path is misrouting the packets in a wrong direction.

A router along the path has the wrong time.

The server is too far away and the packets require too much time to reach it

The server is too loaded and the connection could not be handled in time

The “time exceeded in-transit” ICMP message is generated when a packet’s Time-To-Live (TTL) field reaches zero before reaching its destination. This usually occurs when the packet has traversed too many routers (hops), indicating that the destination is too far away or there is a routing loop causing excessive hops.
* TTL Field: Every IP packet has a TTL field which decrements by 1 every time it passes through a router. When TTL reaches zero, the packet is discarded and an ICMP “time exceeded” message is sent back to the sender.
* Network Latency: High latency or excessive hops can cause packets to expire in transit, leading to this ICMP message.

NO.85 Refer to the exhibit.

Drag and drop the code from the left code from the left onto the item number on the right to complete the Meraki code to obtain a list of client which have used this network.

Explanation:

1 – d, 2 – f, 3 – b, 4 – h, 5 – i, 6 – j, 7 – g, 8 – a, 9 – c, 10 – e

NO.86 Drag and drop the capability on the left onto the Cisco compute management platform that supports the capability on the right.

Explanation

NO.87

Refer to the exhibit. An engineer must authorize a REST API call. The API password is “Cisco123!”. Which Bash command must be placed in the code to authorize the call?

mkdir API_PASSWORD=Cisco123!

set API_PASSWORD=Cisco123!

cp API_PASSWORD=Cisco123!

export API_PASSWORD=Cisco123!

In the provided Python code, the API_PASSWORD is retrieved from the environment variable API_PASSWORD. To set this environment variable in a Bash shell, the correct command to use is export.
This command sets the environment variable for the current shell session and any child processes.
* Bash Command: export API_PASSWORD=Cisco123!
This command ensures that the environment variable API_PASSWORD is set to “Cisco123!” and can be accessed by the Python script.

NO.88 Refer to the exhibit.

What is the value of the node defined by this YANG structure?

Option A

Option B

Option C

Option D

NO.89 What is the function of an Ethernet switch in a networking environment?

to block unwanted traffic

to switch a frame from one port to another port based on MAC address

to switch a frame from one port to another port based on IP address

to provide IP addressing to connected hosts

An Ethernet switch operates at the Data Link layer (Layer 2) of the OSI model. Its primary function is to forward frames between devices based on their MAC (Media Access Control) addresses. When a frame arrives at the switch, the switch reads the destination MAC address and forwards the frame to the appropriate port that connects to the device with that MAC address.
MAC Address Table: Switches maintain a MAC address table that maps each MAC address to a specific port. This table is built dynamically as the switch learns the MAC addresses of devices connected to its ports.
Frame Switching: By using the MAC address table, the switch can efficiently switch frames only to the destination port, which reduces unnecessary traffic on other ports and improves network performance.

NO.90 What are two use cause where webhooks are effective? (Choose two.)

Close a session with a web server after a specific amount of time.

Filter out information from a response to an API call

Change the response format or content type of an API call.

Inform a previously defined chat channel after a deployment fate.

Send an email to a customer of an online store after payment is complete

NO.91 Drag and drop the HTTP status codes from the left onto the correct descriptions on the right.

Explanation
1 – B, 2 – D, 3 – A, 4 – C

NO.92 Refer to the exhibit.

OWASP threat does this example demonstrate?

Broken access control

SQL injection

Man-in-the-middle

Cross-site-scripting

The exhibit shows an example of cross-site scripting (XSS), a security vulnerability where an attacker injects malicious scripts into content from otherwise trusted websites. In this case, the alert function is used to demonstrate the potential for XSS attacks, where user input is improperly sanitized, allowing script execution.

NO.93 What is the purpose of the first three pairs of digits in a MAC address?

defines a routing identifier for the client

indicates the IP address of the client in Hex

defines packet forwarding priority sent or received by the adapter

indicates vendor of the network card or adapter

The first three pairs of digits in a MAC address, also known as the Organizationally Unique Identifier (OUI), identify the vendor or manufacturer of the network card or adapter. This part of the MAC address is assigned by the IEEE to the manufacturers, ensuring that each MAC address is unique.
Reference: Cisco DevNet Associate documentation on networking fundamentals, which explains MAC addresses and their structure.

NO.94 Drag and Drop the Bash commands from the left onto the correct actions on the right.

Explanation:

1 – d, 2 – i, 3 – e, 4 – a, 5 – j, 6 – b, 7 – g, 8 – h, 9 – c, 10 – f

NO.95 Package updates from a local server fail to download. However, the same updates work when a much slower external repository is used. Why are local updates failing?

The server is running out of disk space.

The Internet connection is too slow.

The Internet is down at the moment, which causes the local server to not be able to respond.

The update utility is trying to use a proxy to access the internal resource.

NO.96 What is the purpose of running tests before writing code in test-driven development?

to find unexpected failures in the tests

to demonstrate that the tests fail for expected reasons

to ensure that the tests pass

to provide proof of the work carried out
